fiction - Is including a large number of twists a bad thing?

I've been doing some research into twists, and after not knowing how to create one, I'm starting to get a handle on them. Unfortunately, now I'm at the other end of the spectrum, and wondering if I can have too many twists.

Background: To understand where I'm coming from, you have to know that I plan and develop my novels extensively before writing a single word. I know every little turn of the plot, every scene down to the dialogue said. Then I write it.

Creating novels this way allows me to look at the whole plot at once. Mark Baker's answer on this question has introduced me to the concept of drifting off course so that I can twist back to the story. This means I just look at what I need for the story, then find a way to drift away from it so that I can twist to it. Yes! Twists abound!

I'm now realizing that doing that is going to yield a lot of twists, and I'm wondering if there is any problem with that. I want very much to simply say that the more twists the better, and here's why:

I recently finished reading the SYLO Chronicles, by D. J. MacHale. Excellent books, if a little lacking in the area of character development. What made them so great though was the unending twists. The entire setting was a mystery, and every chapter something changes, either making less sense, or making more sense in the wrong direction. Even the final chapter, after the main conflict was all over, was a twist simply through the writing (you'll have to read it; I won't spoil it).

The point is, I loved those books. Nothing was certain, there were twists everywhere, and I loved it. However, I realize that might not apply to all people.

Question: Is there anything wrong with including a large number of twists? I realize twists aren't for everybody. I know that. What I'm wondering is if there are any actual red flags concerning the number of twists to include.

Answer

Readers of popular fiction (usually) want a clear protagonist, a clear goal, and a clear path of the protagonist to that goal. Readers also want the protagonist to struggle for his goal, so that when he achieves it, this achievement will feel deserved and satisfying to the reader. The purpose of twists is to increase the hero's struggle, to raise the suspense, and to make the story generally less predictable and boring.

So twists are a good thing.

But when the protagonist no longer progresses towards his goal but is stuck in an endless succession of twists that keep him from achieving anything at all; or when we read more about the characters that cause the twists than about who we thought was the protagonist; or when we no longer know what end the novel aims for – then you are overdoing it with twists.

In the end, every twist must only distract the hero for a certain time and then help him forward. After a twist, the hero mustn't return to where he was before, but "solving" or "overcoming" the twist must provide him with a means to progress, either toward his goal or in his development as a person (which in turn helps him toward his goal).

I assume you write popular fiction for my answer. In literary or experimental writing there are no rules or conventions.
